Description
'remap_pfn_range' here may map out of size kernel memory (for example, may map the kernel area), and because the 'vma->vm_page_prot' can also be controlled by userspace, so userspace may map the kernel area to be writable, which is easy to be exploitedProduct: AndroidVersions: Android SoCAndroid ID: A-233154555
